Extractive ftir technology-applications in combustion source measurements

摘要

In response to the 1990 Calen Air Act requirements, the Gas Research Institute (GRI) is investigating emissions from industry equipment including glycol dehydrators, internal combustion engines, boilers heaters, and incinerators. To characterize emissions from internal combustion engines reliabily and accurately, GRI developed and validated a method based on extractive Furier Transform Infrared (FTIR) technology. This paper will describe the FTIR test probotocol approved by U.S Environmental Prtoection Agency (EPA), including a brief discussion on external combustion source FTIR measurement experience. In addition, the approach used in reference spectra development and the associated challenges will be described.
